The QSPI spec allows alt to be any size that is a multiple of the
number of data lines. For example, Micron's N25Q128A uses only a
single alt cycle for all read modes (1, 2, or 4 bits depending on
how many data lines are in use).
Reasons to remove TRNG support:
1. M252 just has 32KiB SRAM and cannot afford mbedtls application.
2. Implementing TRNG HAL with PRNG H/W has security concern.
Without free-up of peripheral pins, peripheral pins of the same peripheral may
share by multiple ports after port iteration, and this peripheral may fail with
pin interference.
In Nuvoton, only new-design chips support GPIO input pull-high/pull-low modes.
Targets not supporting this feature are listed below:
- NUMAKER_PFM_NANO130
- NUMAKER_PFM_NUC472
- NUMAKER_PFM_M453
Fix logic error on replying NACK at the end of transfer.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-i2c/
i2c - test single byte read i2c API.
Better IP initialization sequence:
1. Configure IP pins
2. Select IP clock source and then enable it
3. Reset the IP (SYS_ResetModule)
NOTE1: IP reset takes effect regardless of IP clock. So it doesn't matter if
IP clock enable is before IP reset.
NOTE2: Non-configured pins may disturb IP's state, so IP pinout first and then
IP reset.
NOTE3: IP reset at the end of IP initialization sequence can cover unexpected
situation.
On Nuvoton targets, lp_ticker_set_interrupt(...) needs around 3 lp-ticker
ticks to take effect. It may miss when current tick and match tick are very
close (see hal/LowPowerTickerWrapper.cpp). Enlarge LPTICKER_DELAY_TICKS to
4 from 3 to address this boundary case.
Without this override, mpu hal will require 5 mpu regions which exceed 4 mpu
regions supported by M252 (see hal/mpu/mbed_mpu_v8m.c). In this scenario,
we will hit assert error but we actually meet stack overrun first due to just
0x400 bytes for emitting error message. The issue doesn’t occur on other
targets such as M487 because it has 8 mpu regions.
Remove some (Cypress-proprietary) BSP interfaces and hardware initialization
from the BSPs which is better implemented by a library or application firmware.
Move some remaining functionality from common to the individual targets.
Don't malloc during wifi initialization, as that could cause double allocation in some cases.
The thread stack will be allocated by cy_rtos_thread_start if necessary.
Keep vector table and crash data ram in 0x20000000 for
tests-mbed_platform-crash_reporting test.
Move the rest in RAM (0x24000000). This is needed for ethernet and allows
user to use more RAM (512k).

Fixed HAL API implementation for InterruptIn:
- Interrupt was not enabled by default after configuration as it should be.
- Interrupt-to-object linking was not handled properly.
- Add const and static qualifiers in places where they are
applicable but missing
- Remove headers for drivers that aren't implemented yet
- Misc minor bugfixes
